Abstract

A multi-functional CMOS image sensor was designed and fabricated. We designed a sensing circuitry for on-chip electrochemical measurement. We implemented an 8x8 array of the electrochemical measurement pixels onto a 128x128 optical image sensor with a pixel size of 7.5um. We characterized basic properties of the electrochemical measurement pixel and demonstrated its function with an off-chip cyclic-voltammetry measurement.
